Drunk Sister's Bedroom Raid: Ishihara's Younger Brother!

A sultry Tokyo lingerie model is heading home after a long day of shoots when she finds herself in prime target range. Rina Onkai is preparing to celebrate her younger brother Yuzuru’s birthday—a mischievous and darkly seductive teen whose penchant for debauched play always seeks out young male desires. When Rina gets slightly tipsy and accidentally exposes her magnificent cleavage to his hungry gaze, Yuzuru makes a silent vow: tonight belongs to him! Given Rina's stunning physique—every curve perfectly sculpted—and his inherently naughty nature, this seemingly impossible scenario was destined to become reality. Driven by pure adolescent lust and bravado, Yuzuru sneaks into her room while she’s still awake. Fearless of being caught, he lunges at his unsuspecting older sister, immediately gripping her ample breasts and beginning an intense session of sucking that leaves Rina breathless before she can even react. What a delightfully wicked little brother!
